Here's my piecemeal collection rundown:
Tapco Multitool (Armorers Wrench) - Midway says it's discontinued, it's the best one I've used, I found it in stock elsewhere for $80, but I don't think it's worth that price considering the other options on the market. I have/had an ADE from Amazon and it sucked, castle nut section was too big.
I really like these
AR Stoner Roll Pin Starter Punches from Midway. I've got a cheap set from Amazon but these are superior to my cheap ones in every way.
I've got a couple of Aero lowers that use a bolt for the mag catch instead of a pin, and don't think I'm ever to go back to a pin style again. That alleviates the biggest reason for a starter punch, at least for me. Still handy to have the starter punches.
Wheeler punch and hammer set - All of the small punches have a little bend/banana shape to them now. The hammer is usually enough, but I've added a manlier sized non marring hammer to my kit.
Eastwing 12 oz Rubber Mallet - When the hammer in the Wheeler kit isn't quit skookum enough.
Wheeler FAT Wrench torque wrench - not usually necessary for most AR stuff, maybe the occasional free float handguard, but handy for scope rings and the like.
AR Stoner Vice Block Kit - I've built plenty with some card board or rags in as impromptu soft jaws in my bench vice, but this is handy.
Not necessarily dedicated to "Gunsmithing," I've upped my punch game over the years.
Irwin 6 piece kit - may not be this exact set, but similar, I like how long they are.
Astro Pneumatic Tool 1600 - 16 piece punch and chisel set
Matco SPC6PA - 6 piece punch and chisel set, I got these slightly used on eBay for ~$40
Also not necessarily dedicated to "Gunsmithing"
Craftsman 20 Piece, SAE & Metric, Long, Ball Nose, Hex, Sockets - great for lots of non gun things, but really nice for AR pistol grip bolts. That's an eBay link to that kit, but it's the exact set I bought in Feb of '23, same seller, same link. I'm not sure that's an official Cratsman set, I think it's someone selling a bunch of individual sockets as a set. I haven't shopped around lately, but I recall it being the best "name brand" deal when I bought.
I've given "AR build kits" to buddies just getting into the hobby (mostly because of me) as Christmas presents over the year, mostly the essentials:
Same Midway roll pin starter punches as above.
Amazon Chinesium non marring mallet - cheaper alternative to the Eastwing mallet
AR Stoner Armorer's Wrench
Griffin Armament Armorer's Wrench - cheaper alternative to the AR Stoner
AR Stoner Vise Block
AR Stoner Critical Parts Kit - Usually include some kind of "oops kit," even after building/modding several, I've still had detent springs disappear through an invisible dimensional gateway to another universe.
